Laminate foam and methods of making laminate foam

- NOVATION IQ LLC

A method of making laminate foam material is provided. The laminate foam material includes a layer of non-foam material sandwiched between two layers of foam material. The non-foam material is bonded to the foam material, such as with a bonding agent and/or by heating respective surfaces of the foam material until the surface softens or melts. When a heating process is utilized, the non-foam material is pressed against the softened or melted foam material. As the foam material begins to cool, the non-foam material becomes bonded to the foam material. The non-foam material is narrower than the foam material and is positioned relative to the foam material such that the edges of the non-foam material are concealed by the foam material. Foam products, such as foam mats, can be formed from the laminate foam material by cutting across the width of the foam material.

FIELD OF THE INVENTION

The present invention relates generally to laminate foam material and associated laminate foam products. More specifically, the present invention is concerned with methods of fabricating laminate foam material.

BACKGROUND OF THE INVENTION

Laminate foam material is used for a variety of products, including foam mats and foam flotation devices. Laminate foam material is fabricated by bonding multiple layers of foam together. Flame lamination is one method of bonding foam material together.

Flame lamination involves heating the surface of the foam material, such as with an open flame, to soften and/or melt the surface of the foam material. Two pieces of foam material are then pressed together while their respective surfaces are still hot. As the surfaces cool, a bond is formed. Unfortunately, the bonds created are not always sufficient for every application. For instance, in some applications, such bonds can fail, causing delamination. One such instance involves the use of laminate foam as flotation devices. In such instance, multiple layers (often two) of foam material approximately ½ inch to 1 inch each in thickness are flame laminated together to form a mat, often of sizes in the range of five to ten feet (or more) in width and ten to twenty feet (or more) in length. Some such mats, often referred to as lake mats and/or lake pads, are tied up next to a dock or boat, or tied to an anchor and allowed to float in a lake or other body of water and used as a swim platform for entertainment purposes. Often swimmers will jump from a boat or dock onto the mat, and the foam material and/or bond will break apart. Personal-size floatation mats formed from smaller sizes of the same or similar material can also break apart from use and/or abuse by a user. Consequently, it would be beneficial to have alternative laminating processes. Furthermore, it would be beneficial to have stronger bonds so that the laminate foam material will be less likely to delaminate and/or to provide a laminate foam composition that is stronger than those of the prior art.

The lake pad/mat market is driven by the competing factors of durability and cost. Consumers want a low-cost option, but they do not want the pad/mat to tear or rip. Unfortunately, existing low-cost alternatives, such as those that use two layers of 2# or 3# density ⅝″ thick foam bonded together to make a 1.25″ thick mat, are more susceptible to tears or rips than some consumers and manufacturers would like, leading to rejection rates as high as 10%. Consequently, it would be beneficial to have a low-cost alternative that is less susceptible to tears and rips so that the rejection rate can be reduced without significantly increasing the cost of the product.

SUMMARY OF THE INVENTION

The present invention comprises a superior laminate foam material for use in forming a laminate product and a method of making the same. In some embodiments, such as shown in FIG. 3, the foam material includes a first layer of foam material, a second layer of foam material, and a first layer of non-foam material that is bonded there-between. It will be understood that in some embodiments the layer of non-foam material is formed from a foam material having different properties from one or more layer of foam material. In some such embodiments, the layer of non-foam material is formed from a foam material having high tensile strength while one or more layer of the foam material is formed from a foam material having lower tensile strength.

In some embodiments, the layer of non-foam material extends substantially between opposed first and second ends of the foam material. In this way, the entire length of the foam material is bonded to the non-foam material. In some embodiments, the non-foam material extends partially from a first side of the first layer of foam material to a second side of the first layer of foam material.

In some embodiments, a second layer of foam material is bonded to the first layer of foam material and to the non-foam material such that the non-foam material is secured between the first and second layers of foam material. In some embodiments, the second layer of foam material is substantially the same width as the first layer of foam material but wider than the non-foam material. In some such embodiments, such as shown in FIG. 3, the non-foam material is displaced from opposed sides of the foam material such that the foam material defines opposed first and second strips of material where the first and second layers of foam material are bonded directly to each other and a center strip of material positioned between the first and second strips of material in which the first and second layers of foam material are each bonded to the non-foam material. In this way, the edges of the non-foam material are concealed by the foam material, thereby reducing risk of damage to, injury from, and/or otherwise associated with the non-foam material.

In some embodiments, the laminate foam material includes one or more additional layer of foam material bonded to the first piece of foam material such that the first piece of foam material is positioned between the additional piece of foam material and the second piece of foam material. In some such embodiments, an additional piece of non-foam material is positioned between the first piece of foam material and the additional piece of foam material. In other embodiments, a plurality of pieces of foam material are bonded together. In some such embodiments, a piece of non-foam material is positioned between at least some of the plurality of pieces of foam material.

The present invention further includes a method of making laminate foam material for forming a laminate product of the present invention. In some embodiments, a bonding agent is utilized to bond one or more layer of the laminate material to an adjacent layer of the laminate material. In some embodiments, a top surface of a first piece of foam material is heated, such as with an open flame, so as to create a thin layer of softened and/or melted foam material. A first layer of non-foam material is then pressed against the top surface of the first piece of foam material so as to bond the first piece of non-foam material to the top surface of the first piece of foam material. In some such embodiments, a bottom surface of the second piece of foam material is heated and pressed against the top surface of the first pieces of foam and non-foam material so as to bond the first and second pieces of foam material together with the first piece of non-foam material bonded there between. In some such embodiments, the first and second pieces of foam material are heated simultaneously or nearly simultaneously such that the top surface of the first piece of foam material and the bottom surface of the second piece of foam material are each softened and/or melted when the first and second pieces of foam material are pressed together.

The foregoing and other objects are intended to be illustrative of the invention and are not meant in a limiting sense. Many possible embodiments of the invention may be made and will be readily evident upon a study of the following specification and accompanying drawings comprising a part thereof. Various features and subcombinations of invention may be employed without reference to other features and subcombinations.

The present invention further includes a method of making the laminate product 100 of the present invention. In some embodiments, a bonding agent is utilized to bond one or more layer of the laminate material to an adjacent layer of the laminate material. In some embodiments, a top surface of a first piece of foam material is heated, such as with an open flame, so as to create a thin layer of softened and/or melted foam material. A first piece of non-foam material is then pressed against the top surface of the first piece of foam material so as to bond the first piece of non-foam material to the top surface of the first piece of foam material, thereby creating a first 10 and second 20 layer of the laminate product 100 formed from a foam material and a non-foam material, respectively. In some embodiments, the method further includes heating a bottom surface of a second piece of foam material, such as with an open flame, so as to create a thin layer of softened and/or melted foam material and pressing the first and second pieces of foam material together so as to bond the first and second pieces of foam material together with the first piece of non-foam material bonded there between, thereby creating a laminated product 100 having first 10, second 20, and third 30 layers. In some such embodiments, the first and second pieces of foam material are heated simultaneously or nearly simultaneously such that the top surface of the first piece of foam material and the bottom surface of the second piece of foam material are each softened and/or melted when the first and second pieces of foam material are pressed together.

In some embodiments, the first piece of non-foam material is at least partially secured to at least one of the first and second pieces of foam material prior to the respective first or second piece of foam material being heated. In some such embodiments, the first piece of non-foam material is pressed against the top surface of the first piece of foam material prior to the top surface of the foam material becoming softened and/or melted. In other embodiments, the first piece of non-foam material is pressed against the bottom surface of the second piece of foam material prior to the bottom surface of the second piece of material being heated.

In some embodiments, a multi-burner flame laminator, such as a three burner flame laminator, is used to bond the foam material together. In some such embodiments, first and second flame bars are each angled relative to respective first and second foam layers as the first and second foam layers are heated simultaneously by respective first and second flame bars. In some such embodiments, one or more flame blocker is used relative to the first and/or second flame bar so as to redirect heat away from the non-foam layer as the first and second foam layers are being heated. In this way, a double-layer of foam material can be formed in one pass while the non-foam layer is protected from heat damage and/or deterioration associated with heat.

In some embodiments, triple-layer foam material and other foam material having more than two layers of foam material can be formed using a flame laminator. In some such embodiments, a first foam layer is heated by one or more flame bar/burner so that the non-foam layer can be bonded to the first foam layer. In some such embodiments, one or more flame blocker is used relative to the one or more flame bar/burner so as to redirect heat away from the non-foam layer as the first foam layer is being heated. In this way, the non-foam layer can be bonded to the first foam layer while protecting the non-foam layer from heat damage and/or deterioration associated with heat. In some embodiments, second and third foam layers are each heated by one or more flame bar/burner so that the second and third foam layers can be bonded to the first foam layer. In some such embodiments, one or more flame blocker is used with the one or more flame bar/burners so as to redirect heat away from the non-foam layer as the second and third foam layers are being heated.

In some embodiments, forming the foam product 100 includes cutting the laminate foam material along its entire width so as to create at least part of the foam product. In some embodiments, the material is further cut at one or more location along its length. In some such embodiments, the foam material has an original width of approximately 75 inches and is cut down to a width of between approximately 70 and 72 inches.

In some embodiments, cutting the laminate foam material along its width includes cutting the non-foam material such that the non-foam material is at least partially exposed at one or more end(s) of laminate product 100. In other embodiments, the non-foam material is sized and spaced and the process of cutting the material along its length is coordinated with the sizing and spacing of the non-foam material such that cutting the material along its length does not include cutting the non-foam material.
